There are two types of Growth Passes: Rank and Synthesis.
These passes allow you to earn rewards based on your player rank or the number of times you've performed synthesis.
The Rank Pass allows you to earn Experience Candy by increasing your player rank, while the Synthesis Pass allows you to earn mana by increasing the number of times you've synthesized items.
Both the Rank Pass and the Synthesis Pass have additional rewards that can be unlocked by purchasing the corresponding Premium Reward Access.
*The Premium Rewards Access needs to be purchased for each of the Rank and Synthesis missions.
